This Standard specifies the quality requirements for the TRIFUSION® PLUS process for glass coating by glass fused to steel of panels intended for use in the construction of storage tanks for uses such as the storage or treatment of industrial effluent, where a wider variability of liquid concentrations exists and the more aggressive environment demands a superior quality. This Standard applies to the glass fused to steel elements of the TRIFUSION® PLUS process. The TRIFUSION® PLUS glass fused to steel coating has been developed with reference to International Standard specifications for glass coatings on bolted steel panels and conforms to EN 15282. TRIFUSION® Standard is the highest level of glass fused to steel in the world, for use in the most extreme of environments. Aggressive chemical and high temperature processes can be considered with this high quality contact surface finish, offering zero discontinuity when tested to 1500 Volts on each and every panel manufactured.
